12D Checking For A Shorted Injector
1. Disconnect injector 6-way connector, then connect an ohmmeter between tan wire of connector and ground.
2. If ohmmeter does not indicate continuity, replace [1][2]power module.
3. If ohmmeter indicates continuity, disconnect injector No. 3 connector. Replace injector No. 4 if continuity still exists or injector No. 3 if it does not.
